Patient's question:
Sometimes, when feeling cold, I experience incomplete urination, which has occurred occasionally in recent years.Doctor's answer:
The color of semen is determined by the components of semen. Semen consists of sperm and seminal plasma. Sperm accounts for only a very small portion, with over 90% being seminal plasma. Seminal plasma is secreted by accessory glands such as the prostate, seminal vesicles, Cowper's glands, and paraurethral glands. Its main component is water, along with various other substances such as fat, protein granules, pigment granules, lipid bodies, enzymes, and fructose. Normal semen is grayish-white or slightly yellowish. If abstinence is prolonged, the color may appear more yellow due to changes in its physicochemical properties, which is perfectly normal.Abnormal semen includes:
- Milky or yellowish-green in color, indicating inflammation in the reproductive tract, likely a purulent infection of the prostate and seminal vesicles.
- Red in color, indicating the presence of red blood cells, commonly referred to as "hematospermia." Hematospermia is most often caused by seminal vesiculitis or prostatitis. This type of hematospermia caused by inflammation is usually light red. If it results from vascular malformation and small blood vessel rupture, the hematospermia will be bright red, accompanied by blood clots.
Advice: Abnormal semen color is not something to be feared. Once the cause or underlying condition is identified and treated appropriately, the color can return to normal.
